If a force of 2n is applied to a 0.5 kg mass, what acceleration should result
The walkway system has an efficiency of 78%. Calculate the power input to the system when
15 passengers of average mass 72 kg are standing on the walkway.
Explain what happen to the object (tranquilizer) motion when projectile angle is set to 90. Does the object motion still considered as a projectile motion? If the answer is NO, please provide the reason.
sits at the red light the stuff toy is stationary relative to you. When the light turns
green and the car begins to accelerate to the right, the stuff toy remains stationary
relative to you until the force exerted on them by the string forces them to follow the
motion of the car. Is Newtonà ¢ s law of inertia true to the observer? What about to you
who is sitting in the car?
A loaded wagon weighing 1000 kg requires 40 kg of force to pull it along a
horizontal surface. If the wagon is pulled for 50 m, calculate the amount of work
done. (rolling resistance is = 0)
Two balls are 8.0 meters apart and moving directly towards each other. If the first ball is moving at a speed of 2.5 ms–1 with respect to the ground and the second ball 3.5 ms–1 with respect to the ground, where will they collide?
A bodyvof mass 12kg travelling at 4.2m/s collide with a sound body of mass 18kg at rest. Calculate their common velocity
a ball is thrown vertically upwards with a speed of 40ms^-1. Find the height of the ball when it is moving at 10ms^-1
i)how much work is done by the force
ii)the final kinetic energy of the block
iii)the final velocity
iv)Using newton's second law,find the acceleration and then the final velocity
